Signal Detection Theory - Stimulus, Person, Observer, and
Signal Detection Theory. A psychological theory regarding a threshold of sensory detection. One of the early goals of psychologists was to measure the sensitivity of our sensory systems. This activity led to the development of the idea of a threshold, the least intense amount of stimulation needed for a person to be able to see, hear, feel, or detect the stimulus.
